Hi Guys
Tonight I was riding my bike home from work when all of a sudden as soon as I started to get up to about 30/35mph this high pitch squeaking noise started coming from the engine, below 35mph all I can is a rattle or scratching like sound but I have no idea what any of this could mean.
I managed to record the noise on my helmet camera and so feel free to have a listen to the video I've attached (Would recommend headphones).

I managed to get the bike back home and so will now not ride it until I know what this problem is. My bike is a 2001 Yamaha FZS600 with 43k on the clock.
Really hope you can help me understand what on earth is going on with my bike, thanks in advance.
Any noise with engine running, bike stationery?,
Did you replace speed rota sensor on front wheel,
Spin wheels check brake calipers aren't seized on , chain to slack/tight or seized links, remove front sprocket cover check front nut & clean out any crap build up.

The bike does not make any noise when stationery, or at least nothing like this noise at all.
The speedy sensor on the front will was replaced less than a month ago at a garage do you think maybe they didn't grease it up?
Well may be! put bike on center stand put some weight on pillion seat to raise front wheel & give it a good spin.
Doubt you'll recreate that noise just by spinning the wheel but obviously give it a go anyway.
It has got a plastic sound to it, so you could well be on the right track with the sensor area being too clean, it should be packed with thick grease before refitting it.
Grease can also keep the sensor housing in place a bit better when putting it all back together as well.

Agree with above. Happened with mine, but straight away after replacing the sensor. A very high pitched whine getting worse the higher the speed. Needs lots and lots of grease.
deffo the speedo drive take it out and re grease it be careful to put it back in properly or the lugs will break off

Could it just be wind noise, vent in top of helmet making noise?
Would make sense it getting louder the faster you go. Just a suggestion.
But my guess would be the same as others as the speedo sensor has recently been replaced.
Hi guys
Thanks so much for all your help and suggestions so far, I got in contact with the garage who did the work for me and showed them the camera footage, they have apologised for what they believe is an error when installing the speedo sensor, they are wanting the bike back in next friday to have a look at the speedo sensor and hopefully to put it in correctly.
Thank again for all your help guys hopefully it turns out just to be the speedo sensor

It must only be a grease thing. The only way to put it in incorrectly would involve not lining up the two lugs properly so when you tighten up the wheel nut it just snaps them off, but that also means the speedo wouldn't work at all either, and you mentioned what speed you were doing so it does appear to be working.
You could always do it yourself, just as a learning curve, as long as you have a decent grease to use.
In the mean time though, i would have to suggest not riding it too much in its current state otherwise it'll end up overheating and possibly breaking anyway.

Hi all
Bit of an update, the front wheel was taken off today and the speed sensor was put in correctly and had a lot of grease around it and so the mechanic believes it should be working fine and not causing the noise. He did however replace my front wheel bearing as the one in the bike had a lot of play in it which he believes could be causing the noise. He put the bike back together and I went for a ride and success the noise has disappeared but now my speedo is back to playing up, the needle just jumps all over the place, it'll show the speed I'm going for a second then drop, then rise then drop again etc, however the new speedo sensor looks fine and so I was wondering could this possibly be the speedo cable playing up?
Hope someone can give some insight?

Definitely the Speedo, not the Rev counter?

An incorrectly routed cable can result in it getting brushed by the heads of the brake disc bolts. Once they’ve worn through the insulation that can give some crazy readings on the speedo.

Nope it's just the speedo, my rev counter is fine, I did a TPS test a few weeks ago and it was perfect, but since my speedo started playing up all I've done is replace the rotor sensor and doesn't appeared to of worked.

:rolleyes
its not a cable drive its electric
If the speedo was working fine before today before the work was done then they have either put it back wrong or snapped the lugs off the rota on reassembly.

That did cross my mind as well, it may well have been fine beforehand, but you can't discount the chance that it may have been misaligned when being put back together.
Only one way to find out though.....

Nope the the rotor sensor is fine I was there to witness the work happen, it had loads of grease in there as well, the front wheel bearing he changed has stopped the annoying noise from the video however my speedo is now just completely useless, I went out for a ride tonight and it is just jumping all over the place, the mechanic said the next thing to change would be the speed cable but I'm wary because clearly changing the rotor sensor did nothing.
